Why is my page loading without any css?
Question
So this problem has been bugging me for a few days now. I've been trying to get a working nightmode switch on my site. I've asked on here before and after what I thought was the solution, using help from this site and stack exchange, I started experiencing an annoying problem.
Here is a video of my problem: https://ryan-simms.com/problem
The problem only occurs when nightmode is enabled and I don't understand what the actual problem is. I've tried all sorts of different JavaScript codes with the same result everytime. Also before anyone says it's because of the DOMContentLoaded bit, I have already tried removing it on only using it when adding the EventListeners on my buttons.
Also I tried to change the way getCookie() works with a few different methods.
Are cookies the right way or is there a better way?
Here is my HTML stripped down to the basics:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8"/>
<title>Ryan Simms</title>
<link id ="pageStyle" rel="stylesheet" href='css/lightStyle.css' type='text/css'>
<script src="scripts/lightSwitch.js"></script>
<script src="scripts/cookie.js"></script>
<link rel='stylesheet' href='https://fonts.googleapis.com/css?family=Roboto' type='text/css'>
</head>
<body>
<script src="lightSwitch.js"></script> <!-- Loads LightSwitch Script -->
<button type="button" id="lightSwitchOn">Turn On Night Mode</button>
<button type="button" id="lightSwitchOff">Turn Off Night Mode</button>
</body>
</html>
Here is my JavaScript:
document.addEventListener("DOMContentLoaded", handleDocumentLoad);
function handleDocumentLoad() {
var style = document.getElementById("pageStyle");
var offSwitch = document.getElementById("lightSwitchOff");
var onSwitch = document.getElementById("lightSwitchOn");
offSwitch.addEventListener('click', lightsOn);
onSwitch.addEventListener('click', lightsOff);
function lightsOff() {
document.cookie = "lights = off; expires = Fri, 31 Dec 9999 23:59:59 GMT";
style.setAttribute('href', 'css/darkStyle.css');
}
function lightsOn() {
document.cookie = "lights = on; expires = Fri, 31 Dec 9999 23:59:59 GMT";
style.setAttribute('href', 'css/lightStyle.css');
}
function getCookie( name ) {
var dc = document.cookie;
var prefix = name + "=";
var begin = dc.indexOf("; " + prefix);
var end = null;
if (begin == -1) {
begin = dc.indexOf(prefix);
if (begin != 0) return null;
end = document.cookie.indexOf(";", begin);
} else {
begin += 2;
end = document.cookie.indexOf(";", begin);
if (end == -1) {
end = dc.length;
}
}
return decodeURI(dc.substring(begin + prefix.length, end) ).replace(/"/g, '');
}
function checkCookie() {
var nightmode = getCookie("lights");
if (nightmode == "off") {
lightsOff();
} else {
lightsOn();
}
}
checkCookie();
}
Here is my default CSS:

Are cookies the right way or is there a better way?
Since you don't care about the cookie on the server side, prefer localStorage . You can replace all of your cookie code with things like
localStorage.setItem('lights', 'off');
if(localStorage.getItem('lights') === 'off') { ... }
Instead of loading a new stylesheet for your night mode, consider adding a .dark class to your body if night mode is on and incorporating the appropriate changes in your main stylesheet.
body {
font-family: 'Roboto';
font-size: 22px;
color: #1C1C1C;
background-color: #FFF;
margin: 0 0 100px;
padding: 25px;
}
body.dark {
color: #FFF;
background-color: black;
}
/*Navigation*/
nav {
width: 100%;
background-color: #D8D8D8;
padding-top: 10px;
padding-bottom: 10px;
}
.dark nav {
background-color: #1C1C1C;
}
